If Frederick County doesn't enforce immigration laws, who will?

The Sun is critical of Frederick County's enforcement of immigration laws ("Frederick's mistaken obsession with immigration enforcement," Aug. 9), but where is the criticism of our elected officials for the non-enforcement of our laws, including immigration? It seems that from the president on down, our officials only enforce the laws they agree with and not the ones with which they disagree. Or the ones that get in the way of their politics. President Barack Obama should not be allowed to exempt businesses from part of ObamaCare while putting the rest of us under its control, nor should cities and counties in Maryland have the authority to ignore immigration law and become sanctuary cities/counties for illegal immigrants.

America is becoming a country where only laws that serve the needs of politicians are enforced instead of all laws. If politicians and the people do not agree with our current laws, change them as provided by the Constitution.
